Bacterivory Enhances the Phototrophic Capabilities of an Obligate Phototrophic Ochromonas sp. (Chrys

Parameters: Chlorophyll

Congratulations to Alice Lie who was awarded a Travel Stipend for her poster presentation at ASLO 2017 featuring our Trilogy Laboratory Fluorometer.

Presentation Overview

• Phagotrophic phytoflagellates are mixotrophic algae that can obtain carbon and energy through both photosynthesis and phagotrophy (bacterivory).

• There is a spectrum of mixotrophic strategies ranging from predominantly phototrophic to predominantly phagotrophic.

• Knowledge of different nutritional strategies and metabolism of mixotrophs will enable a better understanding of the functional roles of mixotrophs in communities.

• Ochromonas is a genus of mixotrophic chrysophytes. Many species are predominantly bacterivores, but Ochromonas sp. strain CCMP1393 is obligately phototrophic.

• This study investigates the gene expression of Ochromonas sp. strain CCMP1393 under different light regimes and bacteria availability.
